The garment 110 may be washed or worn in shower without damaging the electrical components that are permanently disposed into the garment 110. In implementations at least one of the plurality of sensing electrodes 112, the plurality of therapy electrodes 114, and one or more components of the controller 120 e.g. capacitors 403, therapy delivery circuit 202, processor 218 are housed in one or more water resistant housings, or enclosures). However, Freeman does not disclose the frequency of the AC voltage output from the amplifier is in a range of 50kHz to 1MHz. Kirson discloses a garment 62 (Fig. 6A, section 0044) for generating AC voltage with the frequency of the AC voltage output from the amplifier is in a range of 50kHz to 1MHz (section 0066, the frequency of the AC voltages is between 100 and 500 kHz, and in some preferred embodiments, the frequency is between 125 and 250 kHz). This allows for proper AC electric fields at specific frequencies to be delivered for treating tissues of a subject’s body. Therefore, it would have been obvious to one of ordinary skill in the art, at the time of the invention, to modify the device of Freeman by adding generating AC voltage with the frequency of the AC voltage output from the amplifier is in a range of 50kHz to 1MHz as taught by Kirson in order to facilitate proper AC electric fields at specific frequencies to be delivered for treating tissues of a subject’s body.

The illustrated receptacle 50 is operable separate from the glove 10 to, for example, charge the battery pack 22, power another electrical device (not shown), etc.). This allows for the battery of the control circuit to have an easy access to be properly charged. Therefore, it would have been obvious to one of ordinary skill in the art, at the time of the invention, to modify the device of Freeman in view of Kirson by adding a charge port as taught by McIntyre in order to facilitate the battery of the control circuit to have an easy access to be properly charged. Regarding claim 14, Freeman in view of Kirson discloses the invention substantially as claimed however does not does not specifically discloses the charge port is coupled to the at least one battery and the control circuitry, wherein the control circuitry is configured to selectively direct power from the charge port to the at least one battery for charging the at least one battery or to the amplifier for supplying the input voltage. McIntyre discloses the charge port is coupled to the at least one battery and the control circuitry, wherein the control circuitry is configured to selectively direct power from the charge port to the at least one battery for charging the at least one battery or to the amplifier for supplying the input voltage (Fig. 5A-B, 7, section 0063, 0070, the connector plug 258′, 258″ includes the flexible wire/cable 98 extending from the pocket 88, 88″ to connect the battery controller 50′, 50″ (along with the battery pack 22) to the glove circuit portion 256 of the glove 10′, 10″. To connect to the glove circuit portion, 256, the user opens the pocket 88, 88″ to access the plug connector 258 (FIG. 5A), and the receptacle 50′, 50″ (along with the supported battery pack 22) is connected by the connector plug. The illustrated receptacle 50 is operable separate from the glove 10 to, for example, charge the battery pack 22, power another electrical device (not shown), etc.). This allows for the battery of the control circuit to have an easy access to be properly charged.
